You can't fit that much detail into an Op-Ed piece but at least the authors have a go here.
Their conclusion? Education is very teacher centric at present and current computer use in classrooms tends to reinforce that view. There are historical reasons for that however they opine that for the future the 'classroom' must become child or student centric i.e. change from a monolithic teaching structure to modular learning structure. Linux is used as both the example and the means to do this.
Of course we see the benfits of this here in New Zealand with the results from the use of Moodle by the Telford Rural Polytechnic. The case studies from Telford and other NZ academic institutions using Moodle can be found here.
